Nursing wins hands-down.

They get paid more (They do a tonne of work though, I have a couple friends in the nursing program) and they don't have to work with stupid, smelly, children (as much). Teachers do get significantly longer vacations though.

I'm taking the medical laboratory tech route, it's doing all the bloodwork (bloodbank, TBC's, biochemistry, etc), culturing (Seeing if people have a certain disease and what antibiotic kills it [Kinda scary seeing certain strains of strep resistant to all but 2 antibiotics out of a 30 antibiotic test]), and jobs like that which allow the nurses / doctors to do their job.
